Answer:
The correct answer is D. The region that was home to the Sioux was the Central Plains of North America.
Explanation:
The Sioux originally lived in the area to the east of the Great Lakes in North America. Since the beginning of the 19th century, due to the oppression and massacres of the colonists and whites, some of them moved westward to the prairie. Later, part of this group was forced to move and was finally concentrated in several small Indian reservations in South Dakota, North Dakota and other states, with an estimated 45,000 people. Another 2,000 people are in Canada.
